Yes, I had wanted to post about it, but then thought: “Oh, s*d it, nobody else is interested enough to mention it”. And of course, there is the big BUT that it wasn’t for MS.
The limitation I foresee is that it needed nerve fibres from elsewhere in the patient’s body, to act as “scaffold” for the regenerated connections to form along. Obviously, as traumatic spinal injury is - for most people - a once in a lifetime thing, you would not expect to have to repeat the exercise.
But with MS being an ongoing/recurring process, I wonder how many times - if at all - the process could be repeated? Pretty soon you’d run out of places to harvest nerve fibres from. So unless they find a way patients could accept nerve fibres from dead donors (all a bit yucky, not to mention problems with rejection etc.) OR they find a way to grow them artificially in the lab, that looks likely to be the sticking point.
Then again, I don’t know how often, on average, new spinal cord lesions appear in MS. I suppose, if you’re lucky, you might go several years without a catastrophic one forming, and in that case, it would be worth doing the repair, as it could be some time before the benefits are undone. Then again, you might be very unlucky, and get a new lesion just weeks after the op, in which case it would all have been for nothing.
